Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed May 8, 1907. Serial No. 372,465.

To all whom it may concern:

in it known that l. Enwnnn li. Hrss, a citizen of the lhntett States, residing in the borough of Brooklyn. city and State of.

The style of the machine to which this partof the invention relates is therefore a visible writing machine in which, at; the moment of impact of the t vpe against the platen, the ribbon is interposed to eti'ect an impression upon the paper and innnediatelv thereafter it moves away from the printing point to expose to view what has been printed. 'lhere are various styles of such machines and this invention is not restricted in its application to any particular machine of that kind.

lipon pcrusal'ot' this specification, it will become obvious to those skilled in the art that the invention is in no wise dependent upon the mode of operating the type bars or upon other details of construction of a writing machine and that it is equally applicablhv to machines printing upper and lower case in which either the platen or type bar segment is shifted.

The primary point of novelty in this part of the invention is the provision of a bar or part, arranged trmisversely of the machine, operated on depression of the several linger pieces in the lacy board and. so constructed or provided with means that at will of the operator difi'erent ranges of movement are imparted to it on depression of the finger pieces to effect through appropriate actuating-devices ditl'erent ranges of movement of the. obon guide or vibrator. This bar or par'tis preferably the universal bar of the mach'me. If, for instance, the ribbon vibrator be connected by suitable levers with this bar, the zone of the ribbon most nearly adjacent the, printing point will be moved into position to print when a small range of movement is imparted to the bar and when a greater range of movement is imparted to it there will, 0t course. he an -increased amplitude of movement of the. rib-- bon vibrator to bring a zone of the rilbon more remote from the printing 'point -nto.

printing position. Provision made for timely and proper actuation of the ttr-tftl1ltiment and also for an adjustment of tin-parts by means of which the ribbon i. not project'- cd to the printing point ther by a-;laptin t the machine to tencil work. The principles of construction by which these results'may be accomplished and the mcchaniciil details which experience has demonstrated to bepractical and ctiicient are forth.

The invention is shown as applied to a front-strike. bar, l e vlever carriage shift machine, that, being the general style of machine to which the inveiilion littr been hcreiua liter:- set first adapted by me.

The invention also comprises certain improvements relating to guides for the rib bon to and from the vibratofaml he altar-"hment of the ribbon to the ribbon bobbins.

I

The universal bar a. is mounted to turn in f hearings in the ends of arms 6 secured to a transverse shaft 0 inoiinted to rock in bearings in the side plates of the machine. Fixed to the universal bar, preferably at one end, the left hand end,-1s a cam plate (1 having j cam surfaces (1, (Z adapted to bear against a stop plate 0 attached to or formed with a vertically arranged plate e provided with a vertical slot e for adjustable attachment to the side plate of the machine. Springs 1 i applied at their lower ends to the arms 6 and at their upper ends to fixed parts of the frame tend. by their reaction, to elevate the universal bar and maintain the cam plate 5 in Contact with the top stop e. A link 9 (Fig. 12) applied at g to the cam plate (Z below the axis of the universal bar extends forwardly and is attached to the side of a vertically disposed lever h pivoted at its bottom and arran ed adjacent the left hand side plate of the frame at the side of the keyboard. This lever has upon its inner side a lug 7: adapted to engage. either of three notches at the side of a slot in a t ..rizontally disposed plate (F i 8) which may be and preferably is marke with the words Bottom Top Stencil Adjustment of this lever operates, by means of link g, to

lace the universal bar and its cam plate d in different angular positions. hen the lever h is engaged with the intermediate notch marked Top on the plate, the parts are in the position indicated in Figs. 1 and 7 and the top stop 0 is in contact with the high surface of the cam face (1. If the lever be moved to the notch marked Bottom b means of link 9 the lower end of the cam plate d being swung rearwardly, and the cam face (1' remains drawn up against stop e by the springs f, f. This is the condition indicated in Fig. 5 of the drawings. When lever his drawn to the front an engaged with the notch marked Stencilthe top stop plate e is in engagement with he lowor provided with two ribs or pro; ecuons of lflerent heights, the higher one being marked a and the lower one a".

cam face (Z this condition being indicated in Fig. '6. These different positions of the cam plate cause two different planes of normal elevation of the universal bar. I

tigidly secured to rock shaft 0 is a lever arm 2' that extends upwardly in rear of shaft c and forwardly under the universal bar being formed with an open notch or recess in which is seated a reduced circular portion 2' of the universal bar. In close proximity to lever 2' and mounted to loosely rock aboutshaft 0 is an escapement operating lever j I that extends upwardly in rear of the bar and forwardly under the universal b..r, that portion of the universal bar opposite the end of the lever being specially formed as hereinafter descr bed. The universal bar is formed arallel' longitudinal These ribs or projections extend under all the key levers k.

Adjacent the cylindrical reduced portion 2' of the universal bar and immediately opposite or above the end of the escapement operating lever j. the bar is formed with a reduced circular part of less radius than the circular partof the bar having two projections of different heights, the high one being 7 marked j and the low one As will be seen in Fig. 2. the low rib a is diametrically opposite the projection 9' and the higher rib a on the bar is diametrically opposite a circular surface of the bar as is also the higher projection j. The upper end of the escapement lever j is connected by a link m with the escape lever m and the upper end of the ribbon guide vibrating lever 2'- is connected to a link a jointed to the downwardly extending short end 0 of a bell crank lever pivoted at 0 on a downward projection from the carriage shift rail, and whose forwardly extending arm 0 is jointed to the vertically disposed ribbon guide or vibrator 0 The connection between the upper end of lever i and link n is effected by a pin 2" on the side of the lever entering a horizontal r slotn' in the link. A coiled spring p havto the downwardly turned end a of link it tends, by its reaction, to move the link rearwardly moving the front end wall of the ing one end attached to lever i and the other i slot n against the pin 2" and holding vif and p serve to return the parts to normal position. The pmjeetionfij on the universal -bot.toni stop I]. lateral pin in the side of a lever 11' pivoted bar opposite the end of the eseapetnent lever is ofsuch elevation as to engage that. lever and ell'ect the timely operation of the eseapement'. For convenience of description, two dotted eircles .one of the diameter of the z'in a and the other of the diameter of the rib (E -have been placed upon Fig. :2. The key lever when depressed, the parts being in the POSltlOI] indicated in Figs. 1 and 7,1noves through that portion of the diameter between the inner and outer dotted circles before engaging the rib (l If it is desired to print from the lower zone of the ribbon, at greater extent of movement of the ribbon guide is, of course, required and fo! that purpose the parts are shifted as described into the position shown in Fig. 5.

When a key lever is depressed, it engages the universal bir opposite the eseapeinent lever and the parts are so proportioned. as will be apparent from the drawings. that the engagement of the escapement lever occurs at the same stage of depression of the key lever as it did when the parts were in the normal position shown in Fig. 7 for printing from the upper zone of the ribbon.

If it be desired to do stencil work, then the parts are adjusted. by means of the lever /i.to the position indicated in Fig.6 in which the superior elevation of the universal bar occurring because the top stop 1' now rests upon the lower part (1 of the cam has op- -hon vibrating lever 2' before the cst-apemcni 1 arm 0 rearwardly and on account of the arc of movement somewhat downwardly causing-the ribbon vibrator to be held, by reason of pressure of pin'z" against the rear wail of slot 11-. in somewhat lower position than its normal position thereby insuring that the type will not strike the upper edge of the gribhon. The end of the lever g extends (l'fllt'tl to carry the pin 8 to the rear wall of the slot 7/" in link 2 tension of spring 1) t being overcome since that spring can now draw the link 1'- rearwardly no farther because the forwardly extending arm 0- of the ribbon guide. bell crank 15 arrested by its This stop is shown as a at on the downward extension from the front rail of the carriage, and connected at its lower end by horizontally disposed link g with a radially projecting eye g on the under side of the universal bar and the further function of which is described below. In this position of the. parts. seen in Fig, (3. when a key lever I. its-depressedit moves through the diameter included between the outcr dotted circle in Fig. I. and the circular surface of the universal bar. before it engages the bar. The higher projec tion j is now immediately above the end of the eseapement lever and conse neatly} there is but very slight. movement of t e ribwlnelnm Fig. 12,;smarked 2. Its upwardly above the upper edge of the bell crank arm 0- and is provided with a stop pin g that acts as a top stop for that arm and is a positive limit to the upward throw of the ribbon guide. In the position last described, it will be seen that this top stop pin substantially in engagement with the upper edge of the lever arm 0 and positively prevents the ribbon guide from rising. in the central position of the lever 11 (shown in Fig. 9) when the parts are adjusted for printing from the upper or top zone of the ribbon. stop 9" is in line above a recess r in the upper edge of the lever arm 0" positively preventing overthrow of the ribbon guide: and when the parts are in position for printing from the lower or bottom zone of the ribbon. as indicated in Fig. the stop pin 1 will be in the position indicated by the dotted circle to the left (Fig. 9),thatis immediately above a deeper recess 1- in the levor.arm 0* and acts to positively limit the upward throw of the vibrator. ()n the inner side of each arm 5 carnving the universal bar are projecting pins I) with which are to contact the side arms of the usual space bar located in the keyboard. To provide for adjustment in assemblingdhe link 2'; is slit and ex ianded as shown at a (Fig. 10) so that its effective length may bc imzreased by contracting the walls of the slit or do creased by expanding them. The link or is preferably connected with the escapement lever m as follows: The link is made of rectangular or notreircular cross section and tits in a correspondingly shaped aperture in the lower end of the lever and has applied to its rear thr adcd end an adjusting nut. Further to avoid unnecessarily loose. fit without friction of the link in the lever, the lever-is preferably jointed as indicated at 711 The escapement devices may be of any appropriate construction and description of them seems quite unnecessary.

In the machine illustrated..the platen. not shown. is to be shifted. In Fig. 8 is indicated the finger piece of a shift kevlever extended end f, when the key lever is depressed. engages and swings forward an arm F extending from the frame pivoted at t that carries the front rail 2 upon which' the machine, close adjustment of the carriage railt In Fig. 12, the bell crank 0, 0 is pivoted upona sl'iort'downward extension from the frontrail of the carriage and the stop lever q is omitted; if used, the extension from the rail would he carried down snfiiciently to provide a pivot for it in the general manner indicated in Fig. 9.

This invention relates also to the guiding of the ribbon to and from the ribbon vibrator, and to means for attachment of the ribbon to the tapes of the ribbon bobbins.

w, 10, represent the ribbon bobbins; W a reversible ribbon feed mechanism; and W is the usual winding shaft.

:2: indicates the ribbon which passes over idlers Y mounted in brackets at the sides of the machine about in the horizontal plane of the ribbon vibrator and with their axes angularly disposed in lines that meet at a point in front of the machine. These guides serve to give the proper extent of turn or twist to the ribbon so'that it will smoothly enter and leave the vibrating ribbon guide. To prevent disengagement :of the ribbon from the idlers in the event of sutlicient slack of the ribbon occurring, there is provided a horizontal guard plate 3 overlying the idler and having a r' ht angular end attached to the su orti racket. To im ose a slight tensiciii upo li the ribbon betw een each of the spools and its corresponding idler there has been provided a tension guide Z (Figs. It to 16). It is formed of wire bent upon itself at the middle into horizontally disposed U- shape as at z and then the wire on each side of'the U-part is carried backwardly a short distance-along the sides thereof as indicated at z and then they incline upwardly their ends being formed with eyes 2 to receive screws attaching them to the frame of the machine. The elasticity of these wire guides tends to carry the cross bar of the U-part slightly inside of the line the. ribbon tends toassumein passing 'from the bobbinto the idler. A slight tension is thereby imposed u on theribbon. This neraharrangement d'r ibbonbobb ins andi lers is disclosed and claimed in an application filed by me Novemher 15, 1905, Serial No. 287,480 and also in my application, No. 300,039, filed February. 8, 1906 in which the identical arrangement thus far described is fully illustrated except that the tension guides similar to those Z above described are formed of sheet metal. The'said application, No. 300,039, discloses also the same arrangement of ribbon feed and winding shaft. that is illustrated in Fig. 14. Any appropriate feed and winding arrangement may be used and detail description is therefore unnecessary.

Fig. '17 shows, applied to the end of the ribbon a metal ti 1 having a T-head adapted to engage an disengage a slotted metal Lip 2 secured to the tape of the ribbon bob- In Fig. 18, the metal ribbon tip 3 has two arallel hooks adapted to engage apertures 1n the tip 4 secured to the bobbin tape.

In Fig. 19, the ti 5 applied to the end of the ribbon has the orm of a hinge butt; andthe tip 6 applied to the bobbin tape has a hinge pintle to engage it. The arrangement. shown in Fig. 21 is identical with that of Fig. 19 except that the hinged butt is upon the tip of the bobbin tape and the pintle upon the tip of the ribbon.

Figs. 22 and 23 show a means of attaching 95 the tips, whatever may be the character of their interlocking devices, to the bobbin-tape and to the ends of the ribbon and is as follows: A sheet metal plate 7 formed or provided with the interlocking device (w ich 100 may be 'of the hinge butt and int-1e form if Figs. 21 and 19 or such as t ose shown 1n Figs. Hand 18 or of still other varieties) is provided with preferably two tongues 8, 9, extending from the edge of the plate in a di-' rection parallel with the ribbon and with to es 10, 11 arranged respectively at opposits sides of the plate and extending therefrom at right angles to the general direction of the ribbon or bobbin tape. This plate is applied to the end of the tape or ribbon. Then the tongues'S and 9 are turned over upon it to clamp it as seen in Fig. 22. Then the ribbon or' tape is laid over upon the tongues 8, 9, and the side tongues 10, 11 re turned down upon it as in Fig. 23. 13 makes a very firm, tenacious, simple and flat. connection of the sheet metal tips with the ribbon or bobbin tape.
